sArErYswI'rcH ron'y A SUSPENDED Two-RAIL TRACK.

T0 all whomz't may concern:

Be it known that I, NIC KnUMr, a citizen of the United States, a resident of Chicago, county of4 Cook, and State of Illinois, have invented' certain new and useful Improvements in a Safety-Switch for a Suspended Two-Rail Track, of which the following, reference being had to the drawings accompanying and forming a part hereof, yis a specification.

This invention relates to a switch for a two-rail suspended track system, such as is usable in machine and other shops, factories and similar places, for transporting raw, Vfinished andfother material about said factories, etc.

Among the objects of this invention is to obtain a switch which is adapted to support heavy loads, topresent smooth track ways over which carriages having flanged wheels adapted to travel onja suspended two rail track may travel without noticeable jar; to obtain a switch of the kind namedfwhich is easily operated and not'liable to get out of order; and a switch which will not permit a carriage suitable to travel thereover, to run offtherefrom when the switch is not set to make a continuous line `for said carriage.

In the drawings referred to- Figure 1 is'a top plan view of a switch embodying the invention;

Fig. 2 is a vertical sectionof the switch.

Fig.` 3 is a horizontal section on line 3-3 of Fig. 2 viewed in the direction indicated by'arrows, and

Fig; 4L is a section on line 4 -4 of Fig.y 2 viewed in the direction indicated by arrows.

A reference character applied to designate av given part indicates said part throughout the severalfigures of the drawing wherever the same appears. Y

JX representsa longitudinally extending beam to which the track and switch about to be described are suspended.

A'represents the member supportlng the pivotal endofthe switch illustrated and the ends of the rails (BB)"which"eXtendto said pivotal end .of the switch.

The member A comprisesthe web member or base a which is illustrated, in Fig. 2, as rigidly secured to the beam, X by bolts C. C. Said'member A'also comprises a supporting member a1' and avertical web a2 joining said membersaa1 and integral therewith.

idly secured to part a1 of member A by bolts d d. The ends of rails B B rest on chair member D and are rigidly secured thereto. i

represents the boltwhich forms a pivot on which the switch turns and F represents a body member forming one end of the switch whlch rests on `the table formed by parts a1 of member A see Fig. 2) and through which the bolt extends. G represents a chair member similar to member D which is secured to member F by bolts gf q.

II represents rail Vmembers of the switch. I represents members by means of which the rails B and I-I are secured in 'the` chair members D and H,

J J represent angle iron members which are ksecured at one end to member A by bolts y y andl at the other end to member K by bolts 7'1 y1. l

The members A J K form a triangular rigid construction which may be termed the base of the movable rail carrying members of the switch.

Member K is rigidly secured in place by bolts 7c lc to a suspending beam, as X, and said member K is provided with a rail member; (L), on which rail the roller M of the about to be described movable endof ythe switch travels, as the switch is operated;L

N represents a traveling4 member, com-- .secured and on which axle the pulley P is rotatably mounted to travel ontrack L. The lower end n1 supports. the chair member Q, said chair member being rigidly ser cured thereto by bolt g. Y

The member K hereinbefore referred to supports the several chair members Q1 Q1 Q1. which are secured to said member K by bolts g1 g1'. One end of the yswitch rails H H is securediny the chair member Q and the end of the-several rails 'R R which extend fromr the switch are secured in vchair Q1.

lS S representthe Vsafety arms or bars ofv the 'switch which are fulcrumed on pivots T T so that the free ends thereof rest on rails R R of the several tracks leading from the switch when the switch is not adjusted to receive a carriage from said rails -ordischarge one thereonto,'so that the normal position of said safety membersk is with the free ends thereof resting on said rails. S1 represents an abutment on member S adj acentto vthe fulcrum of said leverand .U

represents al longitudinally movable bolt which is loosely mounted in member K. V represents a cam member whichis illustrated as integral with the verticalk portion of traveling member N. y c

lV represents a cable by means of which' traveling member N is moved to the right or left as required. N1 represents a bolt which is yieldingly held in an advanced position by spring 72 and W3 73, Figs. 1 and 2, represent recesses on the side of track member L in which recesses the forward end of boltVV1 is yieldingly held by spring VZ. The entering of said end of said bolt into said recess advises the person operating cable IV that the switch is properly set.`

To operate the switch it is merely necessary to manipulate cable W to move traveling member N, to the right or left (pulley ll3 traveling on rail L), until the bolt VV advises the operator that traveling member N is in proper position. At this time the safety members S S of the rails R R,to which the switch is set are raised" by means of cam V and longitudinally movable bolt U, into the position illustrated by full lines in Fig. 2 and the carriage on'the switch (rails H) may travel to rails R R, or vice versa, underneath said safety members S S.

W'here, as illustrated in Fig. 1, there are three tracks of double rails extending 'from one end of the switch, as the traveling vmember N is set for a given one of said tracks, the safety members S Swhichpertain to a given track is raised from and dropped back to the position indicated by brokenlines in Fig. 1 as traveling member N is set to and moved from the set position relative to said track.

It thus occurs that said safety 'members -S S are at no time in lposition to interfere with the travel of a carriage on rails H H,

such carriage at said time being movable' thereunder, while at all times any of said tracks4 formed by said rails R R, which are not continuous to the rails H H, are closed t0 the travel of a carriage thereon toward the switch by said members S S relating thereto resting thereon. f d

It will be observed, by reference to Figs."

2 and 4 that member F is provided with ak semi-circular flange,1f, at oneend thereof,

the upper faceof `said flange being in subare respectively provided withw a` single ange, on said rails,` with said flange on the outside thereof, (as indicated'by lines Y, Y, Fig. 1,) the rails H, H, may be turned ina horizontal plane, a considerable angular distance without breaking the continuity of rails B, B, and the switch rails H, H.
